Abstract
The invention relates to a bottle cap sealing gasket. According to the bottle cap sealing gasket, inorganic polymer fibers are used as a base material, the two surfaces of the base material are coated with two layers of polytetrafluoroethylene, one side, attached to a bottle cap, of the sealing gasket is made of ballast-surfaced elastic silica gel, the circumference, in contact with the bottle cap, of the sealing gasket is made of wave-shaped elastic silica gel, the portion, in contact with a bottle mouth, of the sealing gasket is provided with a groove according to the shape of the bottle mouth, and therefore the sealing performance of the sealing gasket is improved. The bottle cap sealing gasket is high in strength, capable of being used repeatedly, high in sealing performance, and capable of achieving sealing when an object is stored for a long time and guaranteeing the quality of the object. Pretightening and elastic force compensation of the sealing gasket are achieved through the high elasticity of the silica gel. Materials of the sealing gasket do not contain plasticizers and antiagers of the phthalic acid ester type harmful to the human body. The sealing gasket is high in corrosion resistance.
Description
Technical field
The invention belongs to bottle cap technical field, be specially a kind of bottle cap sealing pad.
Background technology
Gasket seal is a kind of sealing member of using for fluids such as container, machinery, equipment, pipelines, the material sealing.Gasket seal is with metal or the tabular material of non-metal, and through cutting, the techniques such as punching press or cutting are made, for being tightly connected between pipeline, between the parts of equipment and parts, the sealed package of flask etc.By material, can be divided into metallic packing and non-metal gasket seal.Metal have copper backing, stainless steel gasket, iron gasket, an aluminium backing etc.Nonmetallic have asbestos gasket, non-asbestos gasket, paper packing, rubber sheet gasket, a pourable resin chock etc.
In daily life, food packaging bottle generally all needs sealed package, adopts and in bottle cap, configures gasket seal to realize the object of sealing.For papery gasket seal, frangible, in liquid, soak, sealing effectiveness is poor, and can not reuse.Using the high-molecular organic materials such as plastics, rubber as gasket seal or as gasket seal base material, and the blowing paper gasket seal that polystyrene is raw material as take, very easily fractures; It is short to take the gasket seal sealing time that polyethylene, polyvinylchloride be base material, when seal failure, can not carry out sealing compensation, especially in the application of the seal aspect of some volatile substances, as alcoholic beverage, fizz etc., through concentration, the mouthfeel of beverage after a while, great changes will take place; Some bottled material, with acid, alkaline, has corrosive property to gasket seal; The gasket seal of the compound press polish one of heat, employing polystyrene is base material, by the films such as polyethylene, polyvinylchloride and the compound press polish one of base material heat, although improved toughness, the leak tightness of gasket seal, frangibility not, but the polyethylene in food stage gasket of bottle lid material, polyvinylchloride etc., in producing, this type of gasket seal need to add 40%～60% plasticizer to improve its processing characteristics, add aging inhibitor to improve in-use performance, wherein phthalate plasticizers enters human body enrichment meeting teratogenesis, carcinogenic.Therefore, in the gasket seal that is available for users to select, it is very limited having multi-functional gasket seal, researchs and develops functional gasket seal strong, good seal performance and has great importance.
Summary of the invention
The object of the invention is to overcome shortcomings and deficiencies of the prior art, provide a kind of good seal performance, intensity high, can realize the multi-funcitonal bottle top gasket seal of flexible sealing.
The present invention adopts inorganic polymer fiber as the base material of gasket seal.Carbon fiber is carbon content higher than 90% inorganic polymer fiber, axial strength and the modulus of carbon fiber are high, density is low, higher than performance, without creep, and superhigh temperature resistant under non-oxidizing atmosphere, fatigue durability is good, specific heat and electric conductivity are between non-metal and metal, and thermal expansion coefficient is little and have an anisotropy, good corrosion resistance, X ray permeability is good, does not contain plasticizer, aging inhibitor etc.Therefore, select carbon content higher than 90% inorganic polymer fiber as seal gasket for bottle cap base material, intensity is high, corrosion stability is strong, high temperature resistant, be difficult for aging, high comprehensive performance.
At the two-layer polytetrafluoroethylene of base material coated on both sides.Because carbon fiber is oxidized under strong acid effect, if bottled food is highly acid material, gasket seal is easily by acid oxidase, if bottle cap material is metal simultaneously, can there is metallic carbide, carburizing and electrochemical corrosion phenomenon with its compound tense, in order to improve the performance of bottle cap sealing pad, prevent that base material from sealing needs when bottled food is acidic materials, at base material coating on both sides one deck polytetrafluoroethylene, the thickness that contacts bottled material one side is two times of opposite side thickness.
Utilize elastic silica gel to strengthen adhesive ability between gasket seal and bottle cap, strengthen sealing property, realize pretension, the compensation effect of gasket seal.Polytetrafluoroethylene is generally called " non-sticking lining ", is a kind of synthesized polymer material that uses fluorine to replace all hydrogen atoms in polyethylene.This material has the feature of antiacid alkali resistant, anti-various organic solvents, is dissolved in hardly all solvents.Meanwhile, polytetrafluoroethylene has resistant to elevated temperatures feature, and does not resemble polyvinylchloride gasket seal goods will decomposite at leisure harmful hydrogen chloride gas under higher temperature.But its friction coefficient is extremely low, as gasket seal, with bottle cap one side poor adhesive force, open after bottle cap, gasket seal easily comes off, for this reason, contacting the nontoxic elastic silica gel of a side coating one deck with bottle cap, for increasing the adhesive ability between gasket seal and bottle cap, be close to a side with bottle cap and make pitted skin, the gasket seal outer rim contacting with bottle cap is waveform elastic force silica gel, from gasket seal and inner side, sealing bottleneck contact position, to gasket seal outer rim, be elastic silica gel, gasket seal and bottleneck contact position, the groove matching with it according to bottleneck shape and the setting of bottleneck wall thickness, bottleneck edge card is in groove, in order to strengthen the airtight performance of gasket seal, utilize the elastomeric property of elastic silica gel to realize pretension and the compensation effect of gasket seal simultaneously.In pad with bottle in a material contact layer be still polytetrafluoroethylene, with bottleneck realize sealing be elastic silica gel and and elastic silica gel on groove.
Be close to a side with bottle cap and gasket seal outer rim is elastic silica gel, and gasket seal and bottle cap being close to the pitted skin of a side, is at 1cm
230-40 pitting or projection are set on elastic silica gel, and object is the friction force that increases the bottle caps such as pad and metal, prevents that pad from coming off when opening bottle cap.
Seal gasket for bottle cap of the present invention is functional strong, can be applied on the bottle cap sealings such as bottled food, chemical substance, has good beneficial effect.There is very high intensity, can be repeatedly used; Have high sealing performance, sealing in the time of can realizing article and store for a long time, guarantees the quality of article; Utilize the high resiliency of elastic silica gel can realize pretension and the stretch compensation of gasket seal; Gasket seal material is without the harmful plasticizer of Phthalates and aging inhibitor; There is corrosion stability.
